摘要: Abstract Background/Aims : The aim of this study was to identify and characterize hepatitis B virus (HBV)-specific cytotoxic T lymphocytes (CTL) epitopes presented by human leukocyte antigen (HLA)-A*2402, most common HLA class I allele in East Asia. Methods HLA-A*2402-restricted CTL were identified reverse immunogenetics. Immunogenecity these investigated using peripheral blood mononuclear cell (PBMC) from HLA-A24 + patients with acute B. Results An HLA-A*2402 stabilization assay demonstrated that 36 63 HBV peptides carrying anchor residues have high- medium-HLA-A*2402 binding affinity. Two (C117–125 P756–764) the induced peptide-specific CTLs. clones lines specific for killed recombinant vaccinia virus-infected target cells expressing HLA-A*2402, indicating two are HLA-A*2402. These able induce CTLs 7 11 12 B, respectively. Conclusions We immunodominant restricted Because is Asia, a region which there approximately 200 million carriers, will be useful analysis responses
